Role in the story

The Captain relieves his helmsman, deciding he'd pilot the ship for the night.Emerald Jewel comes by and says hello. The two begin to chat.
Emerald is bothered because he can't find any pests on the ship.
The Captain suggests setting up some bait traps to catch them.
Kpangbah says he was struggling to sleep, and that steering his own ship is nice.
Emerald asks if he can steer, but Kpangbah says he's enjoying it to too much himself tonight.
Emerald asks what it's like being the captain. Kpangbah says that he prefers the sea over land, that he considers it to be his home rather than any country.
He further says that he dislikes the war and that he'd not be happy to see either side win.
Emerald asks where the captain lived before he began sailing, so the captain talks about Pololimpopo.
He lost his old job, so became a dockworker there, with one thing leading to another.
It was here he met his wife at a bar in town. 3 years later his only son Bo was born.
Kpangbah has served on 3 different ships, most but not all were alongside his son.
Emerald asks how he met Joyride. Thinking back the Captain remembers it all.Joyride and Sunshine Sea lived above a bar, the same one where he met his wife who worked there.
The Captain's wife, Lesedi, died whilst he was at still at sea. Supposedly from an infection.
Kpangbah says he's been to every city in the continent aside from the deer lands. He's even been to Equestria.
They banter about those old days and Sunshine Sea a bit more before he notices how tired Emerald is.
He tells Emerald to go to bed, and that he'll take Ruby down once his helmsman returns.
The following day he has a meeting with Joyride and Bo, talking about how close they are to the galleon.
Kpangbah says they should intercept it in about a week. Bo brings up the foals.
The captain says he thinks Ruby Rouge would handle hearing the truth well, saying he'd make a good pirate.
He ends the conversation by asking Joyride to go a bit easier on his crew, that he needs them to be able to work.
